Abstract: The purpose of the present study is to investigate the impact of leadership styles on employee job performance on public health care sector of Pakistan. The study examined the effect of transactional, transformational, charismatic, autocratic, democratic, laissez faire leadership styles on employee job performance where power distance played a moderating role in the relationship. Data was collected from 315 nurses of public sector hospitals located in twin cities of Rawalpindi and Islamabad in a non-contrived environment. Findings revealed that power distance moderates the relationship among transactional leadership and employee job performance. The significant link among transformational leadership and employee job performance is also found in the study. Whereas power distance does not moderates the relationship among charismatic, autocratic, democratic, laissez faire leadership styles and employee job performance conversely to previous cross cultural research on leadership. Future research directions are also discussed in the study.
